I have modded a Marantz CD-53 before using Ray's mod list and now I'd like to do my own first mod on a Philips CD-710. I made a list of basic mods based on a lot of threads I've been reading for the past few days.
Would anyone like to check if everything I'm doing is right? I'm aiming for a laid back warm sound and all the parts I've chosen are based on that.
- PSU (picture): replace electrolytic caps with Panasonic FR (triple the capacitance), replace 1N4002 diodes (6535...6538) with BA159. Would it also be good to change the ceramic caps in the red zone? Should I replace diodes 6560/6561 as well?
- Servo (picture): replace electrolytic decoupling caps (marked on schematic). Would higher value caps improve sound?
- Decoder (picture): replace electrolytic decoupling caps with higher value Silmic II/Nichicon FG. Is it useful to replace the ceramics (marked blue) as well?
- DAC & Opamp (picture): replace DAC decoupling caps (marked red) with Oscons (higher value)
- Replace Opamp decoupling caps (blue circles on the left) with Silmic II/Nichicon FG
- Replace DC blocking caps (blue circles on the right) with Oscons. Is it okay to use a slightly higher value for the Oscons?
- Opamp OPA2604
- Low Jitter Clock (Flea clock)
- Damp player with bitumen
Am I doing this right? Did I forget something? I'd be very grateful for feedback so I can improve! 🙂

I'll be ordering parts soon so any comments would be greatly appreciated! Is what I'm doing okay?
Hey there. I've got the same player and I am thinking about modding it. Here's what I have in mind, which is pretty close to what you've done (I assume you've finished your modding by now). I am curious as to how it turned out?

Bridge the analog out, the op-chips. Use some coupling-caps.
Resolder: remove the much solder, use minimal solder, minimal diameter: look through the pcb-holes after! The complete player!!!
PSU: I would not replace the diodes.
The Decoder: I would remove the caps without replace (depends of pcb-layout).
Psu: When different psu with same Volt, use only one for all. Do set a pack of little caps (ca. 20 x 1 mF or more). I would remove the original caps and replace with a/the pack. I would remove any, the most, little bridging caps.
Clock I would not set.
Damping with bitumen is okay. But use not much. Better, you decouple the pcb and the mechanism.
Just my ideas,-)
